Dan,
I will try to later. I run irrigation and dusk to dawn area lights on the same controller. So I have a program for Lights, set to dusk and dawn, and this station I have sequential mode turned off. So this program turns on and will be running while I have another program running my irrigation simultaneously. Then their are some master valve control features which I do not use. So If you you set 3 stations to non sequential. You could put 1 on a program to be on from 4 hours starting at 2am, and run a 2nd program in between that time, with mixed sequential and non sequential stations in the same bunch.
